A few years ago, I was in pretty much the same situation: New Tiger Den Leader after being OA brotherhood in my youth, lodges merged since then. OA was some of my best memories and I just wanted to support the current lodge, even if it was just the yearly fee. They probably had a record of me, but I really had to dig to find my ordeal and brotherhood dates in order to list them on the lodge membership form. I wear the lodge flap, the Cubs are intrigued by it. I sometimes help out the troop, so I guess it seems more 'appropriate' now.
